Analog Devices to buy Alif Semiconductor for $1.35B

Analog Devices and Alif Semiconductor said on 9 September 2026 they have entered a definitive agreement for ADI to acquire Alif in an all-cash deal. The joint company press release puts the upfront price at $1.35 billion.

This is a signed definitive agreement, not a completed merger. Both boards approved it. Close is expected before the end of calendar year 2026, subject to customary conditions and the Hart-Scott-Rodino waiting period.

The number most headlines skip is the extra check. ADI may also pay incremental contingent consideration of up to $200 million. The release does not spell out the triggers, and it does not disclose Alif revenue or a purchase multiple.

Alif, based in Pleasanton, California, makes EdgeAI microcontrollers and fusion processors with integrated neural processing units. The release says its silicon is already shipping in production to consumer and industrial customers, so this is not a paper design house.

ADI frames the buy as Physical Intelligence, systems that sense, reason, and act locally under power, latency, and security constraints. CEO and Chair Vincent Roche said the work sits at the electro-physical interface. Alif co-founder and president Reza Kazerounian said the chips were designed around dedicated low-power neural processing. ADI's company blurb puts FY25 revenue at more than $11 billion.

PJT Partners and Wachtell, Lipton, Rosen & Katz advised ADI. Qatalyst Partners and DLA Piper advised Alif.

Other chip and platform deals on the same tape include Nvidia's $12.9 billion Hugging Face agreement, ASML and TSMC's 12-inch High NA mask plan, Qualcomm's Amazon server-chip warrants, and Nvidia's $3.5 billion MediaTek convertible bonds.

If you model ADI M&A or compete in edge AI microcontrollers, book $1.35 billion as the cash outlay now, keep the extra $200 million as an untriggered liability until earnout terms appear, and do not treat the deal as closed until HSR clears and the year-end close actually happens.
